WINDOW REGULATOR.

Application 11156. March 24, 1924. Serial No. 701,502.

like. v

One of the essential objects of the invention is to provide awindow operating mechanism which maybe mstalledas a unit and which will operate ea sily and steadily for raising and lowering the window.

Another object is to durable mechanism that struction and that can comparatively low cost.

A further object is provide astrong and is simple in conbe manufactured at a to provide a mechaanism of this type which in addition to operating the window,

is also adapted to retain the same in any position of adjustment,

lVith the above and the invention consists tures of construction,

rangement of parts as will be other objects In view 111 certain novel feacombinations and ardescribed and particuarly pointed out in the appended claims.

In the accompanying drawing Figure 1 is a side elevation of a portion of a vehicle body and showing a window control mechanism embodying my'invention applied thereto;

Figure 2 is a sectional view line 22 of Figure 1;

taken on the Figure 3 is a sectional view taken on the line of Figure 1. Referring now to like characters f spending parts the drawing ,in which reference designate correthroughout the several views,

the numeral 1 designates awindow that is adapted to be raised o 2,.preferaloly' of a vehl per portion of the r lowered in a'frame cle body. In the upframe is an opening 3 that is adapted to be closed by the window when in raised position,

while in the lower portion of the frame is a vertical pocket t that communicates with the opening 3 and 1s adapted to reoelve the window when in lowered position. suitable construction,

The window may be of any but is preferably a sashless glass panel that is adapted to slide in suitable guideways 5 secured to the upright members 6 of the frame.

For raising and lowering the window,

preferably provide a supporting arm 7 that is provided at one end with a roller 8 which bears against a channel-shaped strip 9 embracing the lower edg e of the panel 1 and more fully engages a horizontal flange 10 at the lower edge of a bracket 11 secured to the strip 9.

The arm 7 is preferably offset as shown at 12 and is preferably pivotally mounted'at its other end upon .a downward extension 13 of a bracket 1 connecting the upright members of the frame. Journalled in ,a flanged bushing 15 secured to the bracket lt is a stub shaft 16 that preferably ex-' tends through an elongated opening 17 in an actuating arm 18. This arm is preferably pivoted at its lower end upona. pin 19 secured to the supporting arm 7 adjacent to the pivot 20 and is provided at its opposite edges with parallel flanges 21 having spaced notches 22 therein. An operating crank 23 is preferably 'non-rotatively mounted on the shaft 16 at the inner end of the bushing 15 and is provided with a suit-able handle 24, while a disk 25 has a hub portion 26' non=rotatively mounted on the shaft at the other endthereof and is provided upon oneufaoe with a spiral flange 27. adapted to engag-cthe notches 22 in the flanges 21 successively for moving the arm 18 longitudinally to actuate the window supporting arm 7. As shown clearly in Figu e 1 of the drawing, the hub portion 26 of the diskis disposed between spaced washers 28 and 29 respectively on the shaft andthe arm 18 is guided in its longitudinal movement by the washer 29 and .the flange 30 of the bushing 15. Moreover, the inner end 31 ofthe spiral flange 27 on the disk 25 is disposed opposite to the outer end 82, consequently, the flange 27 is always in engagement with at least two of the notches 22 in, the flanges 21 and, as a result, the longitudinal movement of the arm 18 is steady and uniform. i

In orderthat the window maybe operated with the least amount of muscular effort, I preferably provide a suitable coun ter-balancing spring 38. One end of this spring is connected to the pin 19, while the other end is preferably provided with a hook 34 for engagement with any of the spaced openings 35 formed in a longitudinally extending embossed portion 36 of the bracket 14.

In use, the window 1 may be raised or lowered as desired by operating the crank 23 to rotate the shaft 16 to cause the spiral flange 27 to successively engage the notches 22 in the flanges 21 on the arm 18 so that the latter will be moved longitudinally for actuating the window supporting arm 7.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

lVhat I claim as my invention is 1. The combination with a frame and a window movable in the frame, of a bracket secured to the frame, a supporting arm for the window pivoted on the bracket, 21 longitudinally movable arm pivoted directly to the supporting arm, a shaft extending through the last-mentioned arm, and means carried by the shaft for moving the last-mentioned arm longitudinally to actuate the window supporting arm.

2. The combination with a frame and a window movable in the frame, of a bracket secured to the frame, a supporting arm for the window pivoted on the bracket, a longitudinally movable. arm pivoted directly to the supporting arm and having a longitudinally extending slot therein, a rotatable shaft carried by the bracket and extending through the slot in the longitudinally movable arm, means for rotating the shaft, a member carried by the shaft adapted to move the last-mentioned arm longitudinally to actuate the window supporting arm, and

a yieldable eounterbalancing member connected to the bracket and to the window sup porting arm.

The combination with a frame and a window movable in the frame, of a bracket secured to the frame, a supporting arm for the window pivoted on the bracket, a longitudinally movable arm pivoted directly to the supporting arm and having a longitudinally extending slot therein, spaced flanges carried by the longitudinally movable arm having aligned recesses spaced longitudinally thereof, a shaft carried by the bracket extending through the slot in the longitudinally movable arm, means for rotating the shaft, and a member carried by the shaft having a spiral flange engageable'with the notches in the flanges on the longitudinally movable arm for moving the latter to actuate the window supporting arm.

4. The combination with a frame and a .window movable in the frame, of a bracket secured to the frame, a supporting arm for the Windaw pivoted on the bracket, an arm pivotally connected oirectly to the arm aforesaid and having spaced flanges provided with aligned notches spaced longitudinally thereof, a rotatable disk having a spiral flange engageable with said notches for moving the last-mentioned arm longitudinally to actuate the window supporting arm, and means for rotating said disk. 7

The combination with a flange and a window movable in the flange, of a bracket secured to the frame, a supporting arm for the window pivoted on the bracket, an actuating arm pivoted directly to the supporting arm and having a slot therein, a bushing secured to the bracket, a, shaft journalled in the bushing andv extending through the slot in the actuating arm, spaced flanges on the actuating arm having aligned notches spaced longitudinally thereof, a disk on the shaft having a spiral flange engageable with the notchesin the flange on the actuating arm for moving the latter to actuate the window supporting arm, and means for rotating the shaft.

6. The combination with a frame and a. window movable in the flame, of a bracket secured to the frame, a bushing, spaced washers on the shaft, a supporting arm .for the window carried by the bracket, a longitudinally movable arm adapted to actuate the window supporting arm and extending between one of the washers aforesaid and. the flange of said bushing, said longitudinally movable arm having a slot therein receiving said shaft, means for rotating the,

shaft, spaced flanges on the longitudinally movable arm having spaced notches therein,

and a member carried by said shaft having a spiral flange engageable with the notches in the flanges on the longitudinally mov able arm for moving the latter to actuate the window supporting arm.

In testimony whereof I affix my signature.

EVERETT E. LUNDBERG.
